IMPROVEMENT IN SIZING FOR HATS, sa

Specification forming part of Letters Patent No. 40,886, dated December 8, 1863.

To all whom it may concern.-

Beitknown that I, HENRY E. POND, a resident of Franklin, in the county of Norfolk and .State of Massachusetts, have invented a new orImproved Mode of Making Sizing for StiffeningFabrics to be Stamped 0r Molded by Heated Dies or Molds and I do hereby declare.

the same to be fully described in the following specification.

My invention is specially useful on felt, palmleat', or fabric'after having been made up into a hat-body, such as is to be formed or shaped by'heated molds or dies, as my preparation or composition,- while it will insure the requisite stifihess to the body of a hat after being acted. on by the heated dies, will.prevent the'hat-body from adhering to the dies.

Heretofore it has been customary to employ for such purposes an alcoholic solution of shellajc; but this has its disadvantages, and, be

sides, cannot be used wit-l lthe economywhich is incident to my solution.

' Although I employ gum-arabic, alcohol, and

water in manufacturing my preparation, I

wish it distinctly understood that Iiay no claim to them merely in combination, asahydro-alcoholic solution of any well-known gum,

I presume isiiot new.

I have discovered when gum-arabic is dis solved in a hydro-alcoholic solution in which when made of four quarts of water, one quartof proof alcohol, and one and'onehalf pounds of gum-arabic. I have discovered,by combining with the said solution, after it may have been properly made, anotherqnart of water,

that a reincorporation of the creamy matter gather and float'on its top ear-- with the solution, 'will at once take place. I have also found, by repeated experiments, that even when the alcohol and water were combined in the proportioirof one'quart of alcohol to five quarts of water the gum my solution made with such and gum-arabic would still .Tbe attended with a separation of the creamy matter. 7

Some chemical or other changeoraction follows the addition of water to the solution, which not only restores the cream yinatter' to the solution, but prevents it from separating therefrom and rising and floating on it. It is this reapplication of water in, or about in,the proportion herein stated to the hydro-alcoholic solution ot'gum-arabic, made in, or. about in,

the proportions as explained that constitutes a material point in my invention.

In making my sizing preparation, to four quarts of cold water one and one-halt'pounds of gum-arabic'are to be added, and alter the gum may have been thoroughly dissolved in the water the solution should be strained or filtered, and afterwardha've a quart of proof alcohol added to it. It should next be well stirred, and subsequentl-ytbe sufferedto rest for about two hours,'after which one quart of water should be added to and well stirred into;-

it. The solution will then be readyfor use.

A fabric after having been sized with the solution should be su-fler'ed'todry. Previous to bein g pressed orstamped it should be rolled in wet cloths, or be steamed, so as to dampen the size.'

-With mypreparation for sizing fabrics they not only can be stamped evenly and faster and with a better finish, but will be cleaner,

and retain their color to more advantagethan they will with any of the other kinds of sizing as heretofore usually employed.

What I claim as my invention, is- The above-described improvement in making the hydro-alcoholic solution of gum-,for the purpose-specified. I

HENRY E. EOND.
